DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 3 and 4 show the hardware arrangement of an information processingapparatus according to the present invention. The information processingapparatus is shown as being incorporated in a small-size, portablecomputerized electronic data storage device.

As shown in FIG. 3, the electronic data storage device includes ahousing assembly comprising a pair of foldable and unfoldable housings16, 17. The housing 17 has a display unit 1 in the form of a liquidcrystal display unit, for example, for displaying image data suppliedfrom a CPU 21 (FIG. 4) or the like. The display unit 1 has on itssurface an input tablet 2 which may comprise a transparenttouch-sensitive device or the like. A stylus or probe 3, which isusually stored in the other housing 16 when not in use, coacts with theinput tablet 2 for inputting desired data into the electronic datastorage device. The stylus 3 and the tablet 2 jointly have a detectorfor detecting a change in the electrostatic capacitance, for example,between the stylus 3 and the tablet 2. When a certain position on thetablet 2 is pointed by the tip of the stylus 3, the coordinates of thatposition can be detected even without the stylus 3 being in contact withthe tablet 2, and a cursor is displayed on the display unit 1 at theposition pointed by the tip of the stylus 3.

When the stylus 3 is taken out of the housing 16 and its tip is broughtinto contact with the tablet 2, information relative to the condition inwhich the tip of the stylus 3 touches the tablet 2 and the positionwhere the tip 3 of the stylus 3 contacts the tablet 2 is transmitted tothe CPU 21, inputting desired data thereinto. The housing 17 supportskeyswitches 5a, 5b, 5c, 5d, whereas the housing 16 supports keyswitches6a, 6b, 6c, 6d. Signals from these keyswitches are also supplied to theCPU 21.

The housing 16 also has a loudspeaker 7 for producing audible signalsand a battery case 8 for storing a battery. The battery case 8 isnormally closed by a lid which can be opened when it is released by alock mechanism 9 associated therewith. Various electronic circuits andcomponents in the housings 16, 17 are energized when a power supplyswitch 10 on the housing 16 is turned on. The housing 11 has amicrophone 11 on an outer edge thereof for picking up voice messages tobe recorded in a solid-state recording medium. The housing 11 has on aside edge thereof a key pad 12 for recording desired voice messages. Thekey pad 12 includes a recording key 12a, a playback key 12b, a stop key12c, and a volume key 12d for adjusting the level of sound to any one ofhigh, medium, and low levels at a time. When the these keys 12a, 12b,12c, 12d are selectively pushed or shifted, a voice message picked up bythe microphone 11 is recorded, or a recorded voice message can bereproduced by the loudspeaker 7.

The housing 16 also has a socket 13 defined in an outer edge thereof forreceiving an IC card such as of a ROM, a RAM, or the like therein, andan expansional socket 14 defined in the outer edge thereof forconnection to an external device (not shown).

The housings 16, 17 are foldably interconnected by a hinge 15 whichincludes a flexible board for transmitting signals between the housings16, 17. Therefore, the housings 16, 17 can be folded together forstorage or spread out for use without electric disconnection betweenelectronic circuits and components in the housings 16, 17. For example,the electronic data storage device as it is unfolded has a longitudinaldimension of about 29 cm and a transverse dimension of about 20.5 cm,and has a thickness of about 4 cm when folded. The display unit 1 has alength of about 15 cm and a width of about 10 cm.

The electronic data storage device has an electronic hardwarearrangement as shown in FIG. 4. The electronic data storage deviceincludes a CPU 21 to which various components in the form of ICs, etc.are connected through a bus 22.

A ROM 23 which is connected to the bus 22 stores various programsincluding a system program for controlling operation of the electronicdata storage device, a character conversion program for convertingJapanese alphabetical characters into Chinese characters in a wordprocessor system, dictionary data for use with the character conversionprogram, a character recognition program for recognizing handwrittencharacters, dictionary data for use with the character recognitionprogram, and other data.

A working RAM 24 and a backup RAM 25 coupled to a power supply 26 arealso connected to the bus 22.

A timer IC 27, which is also energized by the power supply 26, countsclock pulses generated by a quartz oscillator 28 and constantly producespresent data relative to year, month, date, and time.

The display unit 1 shown in FIG. 1 is controlled by a display controller29 which is controlled by the CPU 21. Display data generated by the CPU21 are supplied to the display controller 29 and written into a V-RAM 30through the display controller 29. The display data stored in the V-RAM30 are then supplied to the display unit 1 under the control of thedisplay controller 29.

The tablet 2 combined with the display unit 1 and the stylus 3 areconnected to the bus 22 through a tablet interface 31. Therefore, datawhich are written on the inlet tablet 2 with the stylus 3 are suppliedthrough the tablet interface 31 to the CPU 21.

A voice signal picked up by the microphone 11 is converted by asolid-state recording processor 32 into a digital signal, which isstored in the backup RAM 25 under the control of the CPU 21. When voicesignal data stored in the backup RAM 25 are retrieved, they areconverted by the solid-state recording processor 22 into an analogsignal, which is supplied through a mixer 33 to the loudspeaker 7.

A dialer 34 produces an audio signal, which corresponds to a dual tonesignal of a push-button dialing system, in response to data indicativeof a desired telephone number from the CPU 21. The audio signal issupplied from the dialer 34 through the mixer 33 to the loudspeaker 7.

A key interface 35 is supplied with signals from the key switches 5athrough 5d, and the key switch associated with the stop key 12c. The keyinterface 35 converts the supplied signals into signals which aresupplied to the CPU 21. Signals from the key switch associated with thepower supply switch 10, the key switches 6a through 6d, and the keyswitches associated with the keys 12a, 12b, 12d are supplied to theinterface 35 through a power supply 36. When any one of these keyswitches is actuated, the power supply 36 is first turned on, andthereafter the signal from the key switch is supplied to the interface35.

Interfaces 37, 38 for connection to an IC card and an external circuit,respectively, are connected in the sockets 13, 14, respectively.

Now, operation of the electronic data storage device will be describedbelow. First, a process of retrieving and deleting or shredding segmentdata which have been stored in the V-RAM 30 by the CPU 21 will bedescribed with reference to FIGS. 1A through 1C and 5A through 5I.

When the power supply switch 10 on the housing 16 is pushed, an array 40of irons, i.e., graphic symbols on a menu that are accompanied bycorresponding characters, is displayed in a hatched area 50 of thescreen of the display unit 1 as shown in FIG. 5A.

When the stylus 3 is brought into contact with a "WRITE" iron 51representing a pencil on a righthand portion of the hatched area 50,characters "ACTION" 51a, "CONNECTION" 51b, and "REPORT" 51c aredisplayed on an edge of the righthand portion of the hatched area 50 ina step ST1 (FIG. 1A). The characters "ACTION" 51a, "CONNECTION" 51b, and"REPORT" 51c are also displayed when an icon "PROCESS" 52 or "RESERVE"53 is touched by the stylus 3. Then, the tip of the stylus 3 touches"REPORT" 51c to display a report image 70 on the display unit 1. Theuser can draw any desired images in the report image 70. At this time,however, it is assumed that the report image 70 contains a rabbit 71which is stored in a first page of segment data stored in the V-RAM 30that are to be shredded.

Then, a "SHREDDER" icon 54 is touched by the tip of the stylus 3 in astep ST2. When the tip of the stylus 3 is moved from the "SHREDDER" icon54 into a displayed active area beyond a line 72 in a step ST3 as shownin FIG. 5A, an enlarged shredder image 74 is displayed in an image frame73 (FIG. 5A) in the report image 70, the shredder image 74 including thenumber of pages "0" to be shredded at a position where the tip of thestylus 3 has left off. At the same time, the "SHREDDER" icon 54 iserased. The shredder image 74 also includes a graphic representation 81of a shredder.

After the step ST3, the CPU 21 resets B (back) and F (forward) pagecounters to zero in a step ST4. These page counters represent datastored in back and forward areas of the V-RAM 30, and operate whenrespective B and F keys 75, 76 for turning over pages in the reportimage 70 as shown in FIG. 5B are touched by the tip of the stylus 3.

In a next step ST5, only a "FIRST" key 77 in the window of the shredderimage 74 is enabled, while other keys for indicating pages which aredisplayed in the window are disabled and covered with halftone dotmeshing. Specifically, a "CANCEL" key 78, "LAST" key 79, and a "START"key 80 are disabled.

The tip of the stylus 3 touches the B key 75 or the F key 76 to selectsegment data to be shredded in a step ST6. If the B key 75 is touched bythe stylus 3 four times, then first through fourth pages of segment dataare successively "turned over" in the display unit 1. These pages aresuccessively displayed in the display unit 1 until the fourth page whichrepresents the segment data containing an image 82 of an automobile, forexample, is displayed as shown in FIG. 5C. The segment data themselvesdo not contain page numbers because it would be cumbersome to change,increment, or decrement page numbers in the displayed segment data eachtime they are deleted.

While the pages are being turned over, the shredder image 74 remainsunchanged except the page number. Then, the CPU 21 determines in a stepST7 whether the "FIRST" key 77 is touched by the stylus 3 or not. Ifnot, then control returns through another processing step ST8 to thestep ST7 again. If the "FIRST" key 77 is touched by the stylus 3 in thestep ST7, then control goes to a step ST9 in which the "LAST" key 79 andthe "CANCEL" key 78 in the shredder image 74 are enabled. The number ofpages to be shredded is set to "1" in a step ST10, and then the firstaddress of the displayed page is stored in a memory X in a step ST11.Thereafter, the CPU 21 determines in a step ST12 whether the B key 75 orthe F key 76 is touched by the stylus 3 or not. If the B key 75 istouched by the stylus 3, then the displayed segment or page number isdecremented by 1 in a step ST13 (FIG. 1B), and the B counter associatedwith the B key 75 is incremented by 1 in a step ST14. Then, the sum of 1and the absolute value |B-F| representing the difference between thecounts of the B and F counters is displayed as the page number in a stepST15. Control then goes from the step ST15 back to the step ST12. If theF key 76 is touched by the stylus 3 in the step ST12, then the displayedsegment or page number is incremented by 1 in a step ST16, and the Fcounter associated with the F key 76 is incremented by 1 in a step ST17.Then, the sum of 1 and the absolute value |B-F| representing thedifference between the counts of the B and F counters is displayed asthe page number in a step ST18. Control then goes from the step ST18back to the step ST12.

If neither the B key 75 nor the F key 76 is touched by the stylus 3 inthe step ST12, then the CPU 21 determines in a step ST19 (FIG. 1A)whether the "LAST" key 79 is touched by the stylus 3 or not. If not,then the CPU 21 determines in a step ST20 (FIG. 1B) whether the "CANCEL"key 78 is touched by the stylus 3 or not. If the "CANCEL" key 78 istouched by the stylus 3, then the process is canceled in a step ST21.After the step ST21, control returns to the step ST4. If the "CANCEL"key 78 is not touched by the stylus 3 in the step ST20, then controlgoes through another processing step ST22 back to the step ST12. If the"LAST" key 79 is touched by the stylus 3 in the step ST19, then only the"START" key 80 and the "CANCEL" key 78 are enabled in a step ST23 (FIG.1A). Then, the CPU 21 stores the first address of the page whose pagenumber is displayed in the shredder image 74 in a memory Y in a stepST24. The CPU 21 determines in a step ST25 (FIG. 1C) whether thedifference Y-X between the first addresses in the memories X, Y ispositive (Y-X>0) or not. If the difference Y-X is positive, then thepage data between the value X in the X memory and the final address ofthe segment data starting with the value Y in the memory Y areestablished as the segment data to be canceled or discarded in a stepST26. If the difference Y-X is negative, then the page data between thevalue Y in the memory Y and the final address of the segment datastarting with the value X in the memory X are established as the segmentdata to be canceled or discarded in a step ST27.

The steps ST26, ST27 are described in more detail below. If, forexample, successive second, third, and fourth segment data or pagesamong first through fifth segment data or pages are to be canceled ordiscarded, then the first address (i.e., "9020") of the second page isstored in the memory X in the step ST11, and the first address of thefourth page (i.e., "9080" ) is stored in the memory Y in the step ST24.The step ST25 determines whether Y-X=9080-9020=60 is positive or not. Ifthe difference Y-X is positive in the step ST26, the segment data orpage data between the value X, i.e., the first address 9020 of thesecond page and the final address of the page starting with the value Y,i.e., the first address 9080 of the fourth page are established as thepages to be canceled or shredded. Therefore, the second, third, andfourth pages are established as the pages to be canceled or shredded. Ifthe difference Y-X is negative in the step ST27, then the fourth, third,and second pages are set as the pages to be canceled or shredded.

After the successive segment data to be shredded are specified in thestep ST26 or ST27, e.g., after the second through fourth pages to beshredded are identified, the CPU 21 determines in a step ST28 whetherthe key touched by the stylus 3 is the "START" key 80 or the "CANCEL"key 78. If either the key 78 or the key 80 is not touched by the stylus3, then the CPU 21 executes another processing step ST29 and executesthe step ST28 again. If the "CANCEL" key 78 is touched by the stylus 3in the step ST29, then the process is canceled in a step ST30, afterwhich control returns to the step ST4. If the "START" key 80 is touchedby the stylus 3 in the step ST28, the "START" key 80 is displayed in ahatched mode, indicating that the "START" key 80 is activated, as shownin FIG. 5D. The shredding process now starts to be executed. As shown inFIG. 5E, the display unit 1 displays segment data 83, to be successivelyshredded, as they move from the "WRITE" icon 51 toward the displayedshredder 81 in the shredder image 74. The displayed segment data 82 arethen put into a slot 84 of the displayed shredder 81 as shown in FIG.5F, and cut into small shredded pieces 85 as shown in FIG. 5G. Thedisplayed shredded pieces 85 are then placed in a container 86 as shownin FIG. 5H. These images are successively displayed to allow the user toobtain a clear visual confirmation of the shredding of the segment data83. The shredding process which is being executed is displayed asdescribed above in a step ST31. Then, the corresponding segment datastored in the memory are erased in a step ST32, and a message 87indicating that the shredding process is completed is displayed as shownin FIG. 5I in a step ST33. When the user puts the stylus 3 into contactwith a displayed "CONFIRM" key 88, the B and F counters are reset tozero in a step ST34. The program for the shredding process now comes toan end.

A process of retrieving and copying a desired succession of segment dataor pages from the stored segment data will be described below withreference to FIGS. 2A through 2C and 6A through 6R.

When the power supply switch 10 on the housing 16 is pushed, the array40 of irons is displayed in the hatched area so of the screen of thedisplay unit 1 as shown in FIG. 6A.

When the stylus 3 is brought into contact with the "WRITE" iron 51 onthe righthand portion of the hatched area 50, the characters "ACTION"51a, "CONNECTION" 51b, and "REPORT" 51c are displayed on the edge of therighthand portion of the hatched area 50 in a step STE1 (FIG. 6A).

When the tip of the stylus 3 touches "REPORT" 51c to display a reportimage 70 on the display unit 1. The user can draw any desired images inthe report image 70. At this time, however, it is assumed that thereport image 70 contains a rabbit 71 which is stored in a first page ofsegment data stored in the V-RAM 30 that are to be copied.

Then, a "COPY" icon 55 is touched by the tip of the stylus 3 in a stepSTE2, as shown in FIG. 6A. As shown in FIG. 6B, a copying window remainssmall in size in an area positioned above the line 72. When the tip ofthe stylus 3 is moved into an active area beyond the line 72 in a stepSTE3 as shown in FIG. 6B, the copying window is enlarged and displayedas a copy image 91 in an image frame 90 (FIG. 6C) in the report image70, the copy image 91 including the number of pages "0" to be shreddedat a position where the tip of the stylus 3 has left off. At the sametime, the "COPY" icon 54 is erased. The copy image 91 also includes agraphic representation 96 of a copier.

After the step STE3, the CPU 21 resets the B (back) and F (forward) pagecounters to zero in a step STE4. These page counters represent datastored in back and forward areas of the V-RAM 30, and operate whenrespective B and F keys 75, 76 for turning over pages in the reportimage 70 as shown in FIG. 6D are touched by the tip of the stylus 3.

In a next step STE5, only a "FIRST" key 77 in the window of the copyimage 91 is enabled, while other keys for indicating pages which aredisplayed in the window are disabled and covered with halftone dotmeshing. Specifically, a "CANCEL" key 93, "LAST" key 94, and a "START"key 95 are disabled.

The tip of the stylus 3 touches the B key 75 or the F key 76 to selectsegment data to be copied in a step STE6. If the B key 75 is touched bythe stylus 3 three times, then first through three pages of segment dataare successively "turned over" in the display unit 1. These pages aresuccessively displayed in the display unit 1 until the third page whichrepresents the segment data containing an image 97 of a lion, forexample, is displayed as shown in FIG. 6G. The segment data themselvesdo not contain page numbers because it would be cumbersome to change,increment, or decrement page numbers in the displayed segment data eachtime they are discarded.

While the pages are being turned over, the copy image 91 remainsunchanged as shown in FIG. 6E, which shows that no pages are turnedover. Then, the CPU 21 determines in a step STE7 whether the "FIRST" key92 is touched by the stylus 3 or not. If not, then control returnsthrough another processing step STE8 to the step STE7 again. If the"FIRST" key 92 is touched by the stylus 3 in the step STE7, then controlgoes to a step SE9 in which the "LAST" key 94 and the "CANCEL" key 93 inthe copy image 91 are enabled as shown in FIG. 6F. FIG. 6F shows adisplay condition in which the B key 75 or the F key 76 is about to betouched to turn over pages. The number of pages to be copied is set to"1" in a step STE10, and then the first address of the displayed page isstored in a memory X in a step STE11. Thereafter, the CPU 21 determinesin a step STE12 whether the B key 75 or the F key 76 is touched by thestylus 3 or not. If the B key 75 is touched by the stylus 3, then thedisplayed segment or page number is decremented by 1 in a step STE13(FIG. 2B), and the B counter associated with the B key 75 is incrementedby 1 in a step STE14. Then, the sum of 1 and the absolute value |B-F|representing the difference between the counts of the B and F countersis displayed as the page number in a step STE15. FIGS. 6F and 6G showthat the displayed pages are turned over to the first and third pages,respectively. Control then goes from the step STE15 back to the stepSTE12. If the F key 76 is touched by the stylus 3 in the step STE12,then the displayed segment or page number is incremented by 1 in a stepSTE16, and the F counter associated with the F key 76 is incremented by1 in a step SET17. Then, the sum of 1 and the absolute value |B-F|representing the difference between the counts of the B and F countersis displayed as the page number in a step STE18. Control then goes fromthe step STE18 back to the step STE12.

If neither the B key 75 nor the F key 76 is touched by the stylus 3 inthe step STE12, then the CPU 21 determines in a step STE19 (FIG. 2A)whether the "LAST" key 94 is touched by the stylus 3 or not. If not,then the CPU 21 determines in a step STE20 (FIG. 2B) whether the"CANCEL" key 93 is touched by the stylus 3 or not. If the "CANCEL" key93 is touched by the stylus 3, then the process is canceled in a stepSTE21. After the step SE21, control returns to the step STE4. If the"CANCEL" key 93 is not touched by the stylus 3 in the step STE20, thencontrol goes through another processing step STE22 back to the stepSTE12. If the "LAST" key 94 is touched by the stylus 3 in the step SE19,as shown in FIG. 6H, then only the "START" key 95 and the "CANCEL" key93 are enabled in a step STE23 (FIG. 2A). Then, the CPU 21 stores thefirst address of the page whose page number is displayed in the copyimage 91 in a memory Y in a step STE24. The CPU 21 determines in a stepSTE25 (FIG. 2C) whether the difference Y-X between the first addressesin the memories X, Y is positive (Y-X>0) or not. If the difference Y-Xis positive, then the page data between the value X in the X memory andthe final address of the segment data starting with the value Y in thememory Y are established as the segment data to be copied in a stepSTE26. If the difference Y-X is negative, then the page data between thevalue Y in the memory Y and the final address of the segment datastarting with the value X in the memory X are established as the segmentdata to be copied in a step STE27.

The steps STE26, STE27 are described in more detail below. If, forexample, successive second and third segment data or pages among firstthrough fourth segment data or pages are to be copied, then the firstaddress (i.e., "9020") of the second page is stored in the memory X inthe step STE11, and the first address of the third page (i.e., "9080")is stored in the memory Y in the step STE24. The step STE25 determineswhether Y-X=9080-9020=60 is positive or not. If the difference Y-X ispositive in the step STE25, the segment data or page data between thevalue X, i.e., the first address 9020 of the second page and the finaladdress of the page starting with the value Y, i.e., the first address9080 of the third page are established as the pages to be copied.Therefore, the second and third pages are established as the pages to becopied. If the difference Y-X is negative in the step STE27, then thethird and second pages are set as the pages to be copied.

After the successive segment data to be copied are specified in the stepST26 or ST27 and sheets to be printed are set in position, the stylus 3touches the "LAST" key 94, as shown in FIG. 6H. Immediately thereafter,the display unit 1 displays segment data 98, to be successively copied,as they move from the "WRITE" icon 51 toward the displayed copier 96 inthe copy image 74. With the "LAST" key 94 finally touched by the stylus3, the displayed segment data 98 are displayed over the copier 96, asshown in FIG. 6J. Then, a destination where the identified pages are tobe copied is selected in a step STE28. For example, the stylus 3 is putin contact with a displayed WRITE PAGE 99 as shown in FIG. 6K. Then, thenumber of copies to be produced is selected in a step STE29. Forexample, a displayed key 100 (FIG. 6L) representing "2" is touched bythe stylus 3, and the "START" key 95 is touched by the stylus 3. Then,the CPU 21 determines in a step STE30 whether the key touched by thestylus 3 is the "START" key 95 or the "CANCEL" key 93. If either the key95 or the key 93 is not touched by the stylus 3, then the CPU 21executes another processing step STE31 and executes the step STE30again. If the "CANCEL" key 93 is touched by the stylus 3 in the stepSTE30, then the process is canceled in a step STE32, after which controlreturns to the step STE4. If the "START" key 80 is touched by the stylus3 in the step ST30, the "START" key 95 is displayed in a hatched mode,indicating that the "START" key 95 is activated, as shown in FIG. 6L.The copying process now starts to be executed. As shown in FIGS. 6Lthrough 60, a sliding panel 101 of the displayed copier 96 is moved backand forth, indicating that the segment data are copied. After themovement of the sliding panel 101 is finished, the copied segment data98 move toward the "WRITE" icon 51 and are absorbed by the "WRITE" icon51, as shown in FIGS. 6P and 6Q, indicating the copying process, in astep STE33.
